I just got my Space Gray X5 4.8i and put on 22" x 10" front and 22" x 11" rear Monza wheels with Pirelli Scorpion 295/30/22 front and 335/25/22 rear tires. The rims have the machined face with charcoal gray inner spoke surfaces. We used 10mm spacers in the rear, no spacers in front. I'm also lowered with Eibach front springs and custom rear links.
Need to get some more pics and do a formal introduction. This is a really great website and very informative great group of people. I'm very active on
m5board.com (I'm ATLANTA M5 there). Thanks
